     by his own close observation.
     The high light is usually shapeless. both because it <is[?]>commonly unites
     by imperceptible gradations with the <middle tint> .  half light. & because
     it dazzles the eye more than any other part of the object. and so
 5   prevents observation.  If the object be white - or polished - as
     most leaves are - slate roofs - water - or anything wet - &c - the
     high light - in sunshine - is starlike - shapeless - & dazzling.  Whether
     it be shapeless or not - there is never anything seen in it.  It is
     the most conspicuous part of an object . and is seen farthest - the
10   flash from the weathercock of a steeple can be seen before the <steeple
     itself> weathercock itself . and the <white> sunny side of a white house
     will show in clear air like a star . at 12. miles off . nothing else being
     visible - nor any shape in that.    High lights then .  we may
     lay down as a general principle . are when near . shapeless . & without
15   detail . Are seen farther that any other part of the object . but only
     as bright radiating spots.
     The half light. is the part of an object on which its details &
     character are seen - more or less as it is more or less turned from the
     light - and therefore ordinarily - most <wh> on the very edge of the dark
20   side.  It is here that we see the texture of a stuff - the fluting of a column
